Abstract: The invention relates to a tool, suitable for body shops for correcting damaged vehicle body sheets, but also suitable for saving people trapped in a damaged vehicle and also for other applications that require opposite codirectional forces of high intensity with a rectilinear movement of a movable element, which is practical and independent from external energy sources. The tool (1) uses, as source of rotational movement, a common electric screwer (2) connected in a releasable way within the box (70) of said tool, with its driven shaft connected to a screw mechanism which supports in translational movement a movable element (10). The box of the tool has a front face (8) and a rear face (23), arranged at the lend of the side faces (29, 29?) and the lower face kept together by the four screw pulling elements (28, 28?) tightened by respective four nuts (25). On the front face (8) a fixed element (9) is connected, in which telescopically slides the movable element (17) operated by the screwer (2).
